SHADE HOLDER.

Application: fil'ed October 16,1922. Serial No. 594,847.

To all 4.0 ham it may concern I and JOHN Kinny, J r., citizens of theUnited States, residing in the city of Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and useful In'rprovements in Shade Holders; and we do hereby declare the following tobea full, clear, and exact'description of same, reference being had tothe accompanying drawings, and to the reference numerals marked thereon,which form. a part of this specification.

Our invention while being particularly applicable to lighting fixturesfor use in railway cars is also applicable to lighting fixtures forother uses and one of its objects istocombine with such fixtures aholder for the shades orglobes used in connection therewith which willbe eflicient, durable, of simple construction and of low cost tomanufacture, and which willsupport the shade or globe rigidly in placeand be sufficiently elastic or yielding to prevent rattling or breakingunder the jars and vibrations incident to moving cars or other vehicles:and it contemplates the performance of such function without otherassist ing means ofsupport for the shade .or globe.

Another object of the invention is to pro vide a shade-retainer thatwill permit of the shade being forced into position therein or withdrawntherefrom, without danger of dislodgement'of the retainer, when thelat-- be hereinafter fully described andclaimed."

In the said drawings Figure 1 represents a side View ofthe'fixturehaving a shade held therein, and showing one half in'full and onehalf in section. 1 I

Fig. 2 is a broken perspective. view of the body ring, showing provisionfor a modified form of attachment to a supporting medium.

Fig.3 is a broken detached perspective View of the outer ring or casing,shown partly in section. I V

- -Fi g. 4 is a broken, detached, perspective View of the ring whichforms the upper wall of the channel or groove in 'which'theshaderetaining ring is carried.

M Fig. 5 is a similar view of the shade-retaining ring, and Fig. 6 is aninverted-plan view of the same. 1 Similar reference numerals indicatecorresponding parts in all the figures of the drawings, in Fig. 1 ofwhich drawings the supporting ring of the fixture is shown attached to abase plate 1 by which it may be secured tot-he deck-rail of a car or toany suitable supporting surface, while'in Fig. 2

the said ring is shown attached to a contractedvupwardly extension 2which may beprovided with means for attachment to a bracket or othersupport, but asthe invention relates only to the means for holdingtheshade or globe in position the method of its attachment to anyparticular support is immaterial presents itself as most conducive tothat accomplishment, it is obvious, however,that various modificationsmay be made in the structural details without departing from the spiritof our invention, therefore, we do not wish to be ,limitedto the exactconstruction shown in the drawings or described in'thisspecification. 1

Further referring to the drawings and the reference numerals markedthereon, 3 represents the supporting ring ofthe fixture anditcomprisesan exteriorly screw threaded annulus rounded'at its lower edge,at l, and having a reduced extension 5 to which may be attached. eitherof the forms 1 or 2 (shown in Figs. 1 and 2) or'to any other supportadapted to the thing to which the fixture isto be'attached. 6 representsan internally screw threaded ring adapted to .engagethe threads'of'thering 3 and to operate thereon;

this ring, 6, is incased in and carried byan outer ring; or" casing,preferably formedyof sheet metal, towhich it is secured and whichcomprises a vertical ring or'band 7 Whose lower end terminates in aninwardly dis-' posed horizontal flange 8- and Whose upper extensionclips 9, the bandbeing also 'provided with a knurled swaged or beadedportion 10, and a depression 11 forming a seat 7 At the bot-tom of andsefor the ring 6. cured within the casing, above the flange 8', there islocated a ring or collar 12 having a downwardly extending flange 13, andwhich in conjunction with the flange" 8 forms a circumferential grooveor channel 14 the width of which is determined by the depth of theflange 13, the bottom edge of which rests on the flange 8, as clearlyshown in Figure 1. I

The shade retaineris represented by the numeral 15 and it eomprises'asheet metal spring acting ring of substantially the form shown in thedrawings, a section of which is cut away at 16 for a purpose to behereinafter explained, in its formation this ring embodies ahorizontally disposed portion 17 adapted to be loosely mounted in thechannel 14: and, within certain limits, to move freely therein.Continuing from the said horizontal portion the ring, in cross-section,follows substantially the contour of the neck 18 of a shade 19 and thenpartakes of a downwardly and outwardly disposed incline portion 20 whichterminates, just above the outer edge of the member 17, in ahorizontally disposed narrow portion 21 whose func tion is to contributestiffness to the incline portion 20.

In assembling the device the shade-re tainer 15 is first inserted inposition in the channel 14, as clearly shown in Figure 1, which is doneby contracting the same and springing it into place, the open space 16being provided to allow for such contraction in addition to providingfor contraction and expansion of the retainer in performing its functionin holding and releasing the shade.

'The screw-threads of rings 3 and 6 are then brought into operativeengagement, and with the device thus assembled the extension clips 9 arebent inward to project beyond the inside of the ring 6, their functionbeing to limit downward movement of the ring 6 bvcontacting with ashoulder 22 formed on the ring 3 and thus to prevent undue separation ofthe said rings.

The operation of the device is as follows \Vhen a shade is to beinserted the knurled swage 10 is gripped by the operator and the casingturned in a'direction to move the ring 6 downward carrying with it theshade retainer 15', this frees the latter from contact with thebody-ring3"and leaves it free to expand to permit the end of the shade to beforced throughtheopening of the retainer which will then contract andengagethe neck 18 of the shade, as shown in Figure 1,

and as the inside diameter of the retainer is substantially the same asthe outer diameter of the neck of the shade the latter will be held fromfalling of its own weight until it is more firmly secured by reversingthe movement of ring 6, thereby bringing the incline portion 20 intohard engagement with the end 1 of ring 3, which centers and furthercontracts the retainer to hold the shade firmly in position.

e claim as our invention:

1. In a shade holder, in combination, an externally screw threaded bodyring adapted to be attached to a fixed support, a casing ringsurrounding the same and being in threaded engagement therewith, acircumferential channel formed in said casing ring at the bottomthereof, and a resilient shade retainer comprising a singlenon-continuous sheet metal ring loosely mounted in said channel; saidretainer having a portion which in cross section conforms substantiallyto the neck of the shade and an incline portion extending downwardly andoutwardly therefrom adapted to engage the supporting ring upon upwardmovement of the casing ring'and thereby to circumferentially compressthe retainer causing it to grip the shade and hold it firmly therein.

2. In a shade holder, an externally screw threaded body ring adapted tobe attached to a fixed support, a casing ring surrounding the same andbeing in threaded engagement therewith,- a circumferential channelformed in said casing ring at the bottom thereof, a resilient shaderetainer comprising a single non-continuous sheet metal ring looselymounted in said channel and whose normal inside diameter issubstantially the same as the outer diameter of the neck of the shadewhich it is designed to support; the same being capable of sufficientspring action to permit of passage of the end of the shade and to returnto its normal diameter when obstruction thereto is removed, saidretainer havinga shade engaging portion which in cross section conformssubstantially to the neck of the shade; and an incline portion extendingdownwardly and outwardly therefrom, in combination with means forengaging said incline portion to circumferentially contract the retainerand cause the same to grip the shade and hold it firmly therein. I

In testimony whereof we hereunto afiix our signatures in the presence oftwo sub scribing witnesses.
